Bayly Janson-La Palme worked with Lois Green Carr on economic data about colonial Maryland. Ms. Janson-La Palme then did her own work on economic data about Saint Mary's County from 1790-1870. She relied on census data, assessment records, estate inventories, etc. Her dissertation was based on this material, although the analysis in the dissertation only went up through 1840. The voluminous handwritten data was later transcribed onto 5 1/4" floppy disks using PC WRITE. That data was run on the mainframe computer at the University of Maryland. The disks, spread sheets, and other printouts are at the Hall of Records of the Maryland Archives.
This is a copy of sheet 1 of a set of 4 navigation charts of the Potomac River from Point Lookout to Piney Point. Creeks and other locations are named, but not land holders. The topography was artistically rendered on the Maryland side right next to watercourses. Ms. Janson-La Palme had written in pencil the names of coves and creeks on the Virginia side. The chart making was done by the United States Coast Survey. The data was gathered in 1849 to 1860, with publication in 1862.
